 Import Library statement takes way too long to execute when using tunnel

I use a tunnel to connect to the the python remote server on some target.
```
 Import Library    Remote    http://xxx.xxx.xxx.xxx:12345       WITH NAME    MyRemoteLibrary
```
This import takes about 1 minute to execute, because with a ping of 35ms, it will send 292 requests to get the keywords from the server.
Is there a way to improve this? e.g. get all this data with one request?
